Problems solved by technology

[0003] The drill bit sampler is currently the most used sampling device for sampling. Its sampling speed is fast, but its disturbance is large, the sampling is incomplete, and the equipment is heavy and difficult to operate
[0004] The sampling efficiency of the current sampler is low, and because the sludge is relatively slippery, it is easy to lose the sample after the sampling is completed, or the sampling is incomplete, and the stratification of the sludge sample taken by the current sampling device is not obvious enough, and the sludge surface is easily damaged during sampling, resulting in Sludge surface floats, resulting in incomplete sampling

Abstract

The invention discloses a sludge sample collection device for ecological monitoring. The sludge sample collection device mainly comprises an outer shell, a sampling mechanism, a sampling slideway, anairbag mechanism, an attraction mechanism, a propelling mechanism and a hydraulic rod, the sampling mechanism comprises a sampling section, a threaded section, an internal threaded sleeve and a compaction piston, and the compaction piston can slide into the sampling section; a sampling opening is formed in the bottom end of the sampling section, a slope-shaped sampling inner wall is arranged abovethe sampling opening, and an opening and closing mechanism capable of controlling sludge to enter is arranged at the joint of the sampling opening and the sampling section; and the sampling slidewayis divided into a plurality of steps, a leakage net is arranged on the upper surface of each step, and an impact spring for controlling the sliding track of the sampling mechanism is arranged on the inner wall, in the opposite direction of each step, of the sampling slide way. The sludge sample collection device can be used for quickly sampling sludge, can be used for filtering excessive water inthe sampling process and extruding and vibrating the sludge, and is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of sludge collection, in particular to a sludge sample collection device for ecological monitoring and a collection method thereof. Background technique [0002] Sludge sampling is to study the accumulation, distribution, transformation and migration of pollutants discharged into the water body in the sediment. It is a survey method widely used in the fields of environment and hydrology. At present, there are many kinds of sampling equipment for silt. For sandy bottom mud, cone samplers, drill bit samplers, pendent samplers, etc. can be used; when the bottom mud is pebbles, spade samplers and clam samplers can be used. sampling. [0003] The drill bit sampler is currently the most used sampling device for sampling. Its sampling speed is fast, but its disturbance is large, the sampling is incomplete, and the equipment is heavy and difficult to operate. [0004] The sampling efficiency of the current sampler...
